The present invention relates to advertising devices generally and more particularly the invention relates to such devices in whlch a luminous electric discharge device forms a letter and a plurality of such devices make up a word.

The object of the present invention is to provide such are easily and quickly changed. Another object of the invention is to provide such a device in which the entire word or legend is movable. Further objects and advantages attaching to the device and to its use and operation will be apparent to those skilled in the art from the following particular description and from the appended claims.

In accordance with these objects the invention comprises a rod-support and clamp members adapted to support the luminous electric discharge devices on said rod-support. Said clamp members are in two parts and form a letter. The opposite sides of said letter are reflectors and a luminous electric discharge device shaped in the form of said letter is mounted on each side of said letter. The rod-support and therewith the letters attached thereto is revolvable where that is desired.

In the drawing accompanying and forming part of this specification an embodiment of the invention is shown in which Fig. 1 is a front elevational view of a sign made in accordance with the present invention, and

Fig. 2 is a sectional view along the line 22 of Fig. 1 showing in detail the structure of the letter shaped clamp members.

Like reference characters denote like parts in both views of the device.

Referring to Fig. l of the drawing a rodsupport 1 is attached to a wall 2 by rods 3 and 4. A plurality of two sided letters 5 having on each side thereof luminous tubes 8 of the same configuration is clamped to said rod-support 1. The structure of said letters 5 is shown in Fig. 2 in which the rims of the two hollow parts 6 and 7 thereof overlap and are held together by bolts 9 to form a double side letter 5. Bolts 11 serve to clamp said letter 5 on said rod 1. Having this a device in which the letters structure the letters 5 of the sign arequickly and easily attached to and removed from said rod 1 by tightening or loosening said bolts 9 and 11.

The eifectiveness of the above sign is enhanced by causing the rod 1 to revolve and stopping it for a short interval on each half revolution thereof.

While I have shown and described and have pointed out in the annexed claims certain novel features of the invention, it will be understood that various omissions, substitut-ions and changes in the forms and details of the device illustrated and in its use and operation may be made by those skilled in the art without departing from the broad spirit and scope ofthe invention.

What I claim as new and desire to secure byLetters Patent of the United States, is

1. A sign comprising a plurality of letters mounted on a rod-support, said letters being in two parts adapted to clamp said rod, each of said parts having a reflecting surface and a luminous electric discharge device of the same configuration mounted thereon in operative relation to said surface.

2. A sign comprising a plurality of letters mounted on a rod-support, said letters being in two parts adapted to clamp said rod, each of said parts having a reflecting surface and a luminous electric discharge device of the same configuration mounted thereon in operative relation to said surface, said rod being capable of revolving.

In witness whereof, I have hereunto set my hand this 14th day of June, 1932.
